Extracellular signal-regulated kinases

Padmina Shrestha BIO 222 Prof. Bill Thomas 11/03/2014 Kinetochore-microtubule interaction and the role of Aurora kinase B All living organisms are a result of multiple rounds of cell division; new cells can only be formed from pre-existing cells. For the duplication of cells, genetic materials as well as other organelles in a cell have to duplicate in order to pass down the information about how to organize the cells (Alberts, et al., 2008). During S phase of the cell cycle, chromosomes as well

Unlike other blood cells, platelets are small anucleate structures derived from marrow megakaryocytes and thought for almost a century to possess solely hemostatic potentials. Platelets, however, play a much wider role in tissue regeneration and repair and interact intimately with tumor cells. On one hand, tumor cells induce platelet aggregation [TCIPA] known to act as the trigger of cancer associated thrombosis and on the other, recruited to the tumor microenvironment platelets interact directly

Introduction It is astounding that the expression of one protein can be so significant to the health and identity of an individual. The pathway in which the CREB binding protein gene is regulated reveals how intricate the system inside the nucleus of a cell actually is. Every plant and animal has its own set of genomic “instructions”, which it receives from one or more parents. This set of instructions is called deoxyribonucleic acid (DNA) and it is what allows every organism to be its own unique

Significant Role of Hippocampus Hippocampus is a small, curved region, which exists in both hemispheres of the brain and plays a vital role in emotions, learning and acquisition of new information. It also contributes majorly to long term memory, which is permanent information stored in the brain. Although long term memory is the last information that can be forgotten, its impairment has become very common nowadays. The dysfunction is exemplified by many neurological disorders such as amnesia. There

To have the capacity to accumulate every one of the outcomes we will utilize the Fortified Discharge Exhaustion (STED) microscopy, which utilizes nanoscopy methods to recognize more noteworthy detail in a specimen being picture, which is particularly valuable for recognition of dendritic spine development and pliancy. Because of the high force laser vital for STED microscopy, beat excitation will be utilized to restrict photobleaching and test harm. What's more, a calcium fluorescent color will be

Abstract Skeletal muscle adapts to changing physiological demands by altering intracellular programming of gene expression, including the driving mechanisms behind mitochondrial biogenesis and muscle fibre type composition. The transcriptional co-activators PGC-1 and in particular, PGC-1α, have been found to directly regulate these adaptations by activating signaling pathways. Alternatively, signaling pathways can induce PGC-1 expression or activity. The ability of PGC-1 to promote mitochondrial

ERK–mitogen-activated kinase pathways . BDNF and the ERK pathway represent one of the key signaling cascades mediating neurotropic action and synaptic plasticity, and has received considerable recent attention for its potential involvement in the pathophysiology and treatment of BD(Coyle and Duman, 2003). Therefore, Engel et al., 2008 (Engel S.R., Creson T.K., Hao Y., Shen Y., Maeng S., Nekrasova T., Landreth G.E., Manji H.K., Chen G. (2008). The extracellular signal-regulated kinase pathway contributes

Introduction Mental illness is a serious growing issue, not only in the United States, but also around the world. It is estimated approximately forty-three million Americans suffer from a mental illness. The concerning issue however, is that the forty-three million estimated only represent those who have sought diagnosis. Therefore, there may still be a large number of individuals who remain undiagnosed (National Institute of Health, 2013). Although treatment may keep a disorder under control
